Honest Opinion after Bridgen v Hancock: No Third‑Party Opinion Evidence under s 3(4) and a Strict, Belief‑Focused s 3(5)

Court: England and Wales Court of Appeal (Civil Division)
Neutral citation: [2026] EWCA Civ 991
Date: 29 July 2026
Appeal from: [2025] EWHC 926 (KB) (King’s Bench Division, Media and Communications List, Collins Rice J)
Judges: Lady Justice King, Lord Justice Warby, Lady Justice Whipple (judgment of Warby LJ)

1. Introduction

The appeal concerned the operation of the honest opinion defence under section 3 of the Defamation Act 2013, focusing on:

  • s 3(4) (whether an honest person could have held the opinion on the stated factual basis), and
  • s 3(5) (whether the defendant did not hold the opinion, defeating the defence).

The dispute arose from a social media exchange between two former MPs. The claimant posted a tweet linking to an academic article about reported adverse events following Covid vaccination, adding the line: “As one consultant cardiologist said to me this is the biggest crime against humanity since the Holocaust.” The defendant (then a prominent former Cabinet minister) later tweeted, in substance, that a sitting MP had spouted “disgusting and dangerous” “anti-semitic” conspiracy theories. The claimant sued in libel, focusing on the allegation of antisemitic character.

Procedurally, a High Court judge refused to grant the defendant summary judgment on honest opinion (and refused to strike out the claimant’s s 3(5) case), holding that the issues required trial. The Court of Appeal reversed that decision, struck out the claimant’s Reply (so far as it advanced s 3(5)), and entered summary judgment for the defendant.

2. Summary of the Judgment

The Court of Appeal allowed the appeal and held that:

  • s 3(4) objective honesty is assessed without evidence of what third parties thought. The High Court had erred by treating third-party reactions (and potentially reactions to similar statements on other occasions) as potentially determinative. The Court of Appeal ruled that such material is not admissible on the s 3(4) question.
  • On the undisputed, common-knowledge facts about the Holocaust and the pandemic response, an honest person could have held the view that comparing the Covid vaccination programme with the Holocaust was antisemitic in character (even if unreasonable or irrational). Summary determination was therefore appropriate.
  • s 3(5) requires a strict, dishonesty-like pleading and evidential threshold. The claimant’s attempt to infer lack of genuine belief from (i) alleged “unreasonableness”, (ii) motives, and (iii) definitional materials (IHRA, etc.) did not meet the heightened standard. There was no real prospect of proving the defendant did not hold the opinion.
  • Recklessness is not enough under s 3(5). The statute’s test is whether the defendant did not hold the opinion; “reckless indifference” is not a substitute.

3. Analysis

3.1 Precedents Cited

(A) The breadth of “honest opinion” and the low objective threshold

  • Riley v Murray [2022] EWCA Civ 1146, [2023] EMLR 3: Warby LJ reaffirmed his own framing of s 3(4) as the “Objective Honesty Condition”, emphasising its purely objective nature and the generous latitude afforded to opinion. The case was also used to reject artificial constraints on what “facts” may be relied upon under s 3(4) (here, common-knowledge facts about the Holocaust and pandemic).
  • Turner v MGM Pictures Ltd [1950] 1 All ER 449, Silkin v Beaverbrook Newspapers Ltd [1958] 1 WLR 743, Telnikoff v Matusevich [1992] 2 AC 343: These authorities were cited for the established proposition that the protected “honest” commentator may be irrational, obstinate, exaggerated, or prejudiced. The Court of Appeal used them to underline that s 3(4) is not a “reasonableness” test.
  • Tse Wai Chun Paul v Cheng [2001] EMLR 777 and Gardiner v John Fairfax & Sons Pty Ltd (1942) 42 SR (NSW) 171: Lord Nicholls’ articulation of the common law’s objective honesty criterion (“however prejudiced… however exaggerated”) and the “dip his pen in gall” formulation were treated as foundational to the statutory defence’s intended scope.
  • Branson v Bower [2002] QB 737: Central to the Court’s approach to summary disposal. Eady J’s insistence that honest comment should not be whittled away by “detailed and subtle arguments” supported deciding s 3(4) without trial where only one conclusion is reasonably open.
  • Joseph v Spiller [2010] UKSC 53, [2011] 1 AC 842: Used for two purposes: (i) the Supreme Court’s endorsement of Cheng on the meaning of “malice” in the comment/opinion context, and (ii) to reinforce that the crucial question for defeating comment/opinion protection is genuineness of belief, not hostility of motive.

(B) Drawing a firm line against third-party opinion evidence on s 3(4)

  • The Court treated the High Court’s approach—potential reliance on “spontaneous opinions independently expressed” and the “Jewish doctors’ letter”—as legally erroneous.
  • Baturina v Times Newspapers Ltd [2011] EWCA Civ 308, [2011] 1 WLR 1526: Cited to show that even in the “true innuendo” context, evidence of what people understood is controversial; it should not be extended to s 3(4).

(C) The strictness of s 3(5) (dishonesty-like allegations)

  • Horrocks v Lowe [1975] AC 135: Not for importing qualified-privilege malice into honest opinion, but as part of the doctrinal history distinguishing privileged “dominant improper motive” from comment/opinion’s belief-focused test.
  • Somerville v Hawkins (1851) 10 CB 583 and Turner v Metro-Goldwyn-Mayer Pictures Ltd [1950] 1 All ER 449: Used to justify the “heightened” standard: pleaded facts must raise a probability of dishonesty; equivocal facts are “valueless”.
  • Three Rivers District Council v Bank of England (No 3) [2003] 2 AC 1: Invoked for the wider principle that dishonesty cannot be inferred from material equally consistent with non-dishonest explanations; weakly particularised allegations are liable to be struck out.
  • Derry v Peek (1889) 14 App Cas 337: The claimant’s reliance on “recklessness” concepts from deceit was rejected as inapposite to opinion: a statement of opinion is not “false” in the required sense, and s 3(5) sets a single test—whether the defendant did not hold the opinion.

(D) Parliamentary privilege and repetition outside Parliament

  • Jennings v Buchanan [2004] UKPC 36, [2005] 1 AC 115 and R v Chaytor [2010] UKSC 52: The Court rejected the idea that repeating outside Parliament what was said in Parliament evidences bad faith. Those authorities concerned Article 9 of the Bill of Rights issues (whether courts may examine parliamentary proceedings), not inference of dishonesty.

(E) Case-management context

  • Sussex v Associated Newspapers Ltd [2023] EWHC 3120 (KB): Cited as a useful summary of honest opinion principles, but the Court of Appeal found the High Court’s application flawed.
  • Iqbal v Geo TV Ltd [2024] EWCA Civ 1566, [2025] KB 357: Used to justify summary resolution to reduce “chilling” effects of costly litigation on reputation and free expression.

3.2 Legal Reasoning

(A) s 3(4): the “Objective Honesty Condition” is for the court, by argument, without third-party opinions

The Court of Appeal’s central contribution is its clear ruling that s 3(4) is to be answered by the tribunal’s own objective evaluation of: (i) the defendant’s opinion as expressed, (ii) the indicated basis, and (iii) the relevant facts existing at publication (including common-knowledge facts), not by adducing evidence of the reactions, condemnations, or endorsements of third parties.

The Court gave both principled and pragmatic reasons:

  • Principle: like “ordinary meaning” in defamation, the court uses a hypothetical construct (here, the honest person) and decides without evidence of what actual readers or commentators thought.
  • Pragmatism: admitting such material would invite complex “satellite” disputes—about sampling, representativeness, the factual basis of third-party opinions, and the honesty of those opinions—yet would rarely be decisive (since honest opinion protects a lone, “crank” viewpoint).

On the merits, the Court held the comparison between the Holocaust (a deliberate genocidal campaign) and the Covid vaccination rollout (a public health initiative at least partly aimed at saving lives) could objectively support an honest person’s view that the comparison “minimised or trivialised” the Holocaust and could be characterised as antisemitic in that sense. The question was not whether the claimant’s tweet was antisemitic, but whether the defendant’s opinion that it was fell within the wide scope of protectable honest opinion.

(B) s 3(5): “Dishonesty Disqualification” demands a probability-based, strictly particularised case

Warby LJ’s analysis strongly re-centres s 3(5) on one question: did the defendant genuinely hold the opinion expressed? Hostility, spite, political motive, or intent to injure do not defeat the defence unless they support an inference that the opinion was not genuinely held (per Tse Wai Chun Paul v Cheng and Joseph v Spiller).

The Court held the High Court applied too low a standard—treating the matter as “equivocal” and better left to trial—when the law requires pleaded facts that are more consistent with dishonesty than not. On the claimant’s pleaded and proposed amended bases (IHRA materials; the word “since”; absence of a truth plea; continued publication; the defendant’s education; alleged motive), none generated a probability that the defendant did not believe his expressed opinion.

Two clarifications are particularly significant:

  • Objective unreasonableness is not a route to s 3(5): once the court has accepted under s 3(4) that the opinion is one that an honest person could hold even if irrational, it is incoherent to say its “unreasonableness” itself proves non-belief.
  • Recklessness does not satisfy s 3(5): the statutory test is not “reckless indifference”; it is non-belief. One cannot be recklessly indifferent to whether one holds an opinion: one either holds it or does not.

(C) No evidential burden on the defendant absent a cogent s 3(5) case

The Court rejected the idea that the defendant had to “explain” his state of mind to defeat s 3(5). The burden rests on the claimant to plead and prove non-belief. Without a properly particularised, probability-raising case, the defendant’s silence cannot cure deficiencies.

3.3 Impact

  • Evidence boundary for s 3(4): parties should expect courts to exclude attempts to prove “objective honesty” by reference to: (i) reaction tweets, (ii) open letters, (iii) institutional definitions, or (iv) what other commentators said about comparable statements. The s 3(4) inquiry is primarily legal-argument-driven, not evidence-driven (beyond the relevant facts and context).
  • More summary judgments in honest opinion cases: by “grasping the nettle” and resolving s 3(4) on the materials available, the Court signals that where only one outcome is reasonably open, courts should consider early disposal to reduce chilling effects (cf Iqbal v Geo TV Ltd).
  • Harder to plead and run s 3(5): claimants will need sharply pleaded facts supporting a probability of non-belief. Assertions that an opinion is “wrong”, “inconsistent with definitions”, or “politically motivated” will often be insufficient without more.
  • Reputational and political-speech disputes: the judgment reinforces that robust language in political debate can still be protected as honest opinion, and that the law does not confine honest opinion to measured or “fair” commentary.

4. Complex Concepts Simplified

  • Honest opinion (Defamation Act 2013, s 3): a defence where (1) the statement is opinion, (2) it indicates its basis, and (3) an honest person could hold it on the relevant facts (s 3(4)).
  • Objective honesty (s 3(4)): not “is the opinion correct?” or “is it reasonable?” but “could an honest person hold it on these facts?”—a broad standard that tolerates exaggeration and even irrationality.
  • Dishonesty disqualification (s 3(5)): even if s 3(4) is satisfied, the defence fails if the claimant proves the defendant did not actually hold the opinion. Motive may be relevant only as evidence of non-belief, not as a standalone defeater.
  • Summary judgment (CPR 24.2): a procedure to decide issues without a full trial where the other side has no real prospect of success and there is no other compelling reason for trial.
  • “Malice” (historically): in honest comment/opinion it means non-belief (per Tse Wai Chun Paul v Cheng), not “dominant improper motive” (the qualified privilege concept from Horrocks v Lowe).

5. Conclusion

[2026] EWCA Civ 991 materially clarifies the modern honest opinion defence in two ways. First, it establishes that third-party reactions and comparable-commentary evidence are not admissible to decide s 3(4); the court decides objectively, by its own evaluative judgment, whether an honest person could hold the view on the relevant facts. Secondly, it tightens the practical operation of s 3(5): allegations that the defendant did not genuinely believe the opinion must meet a heightened, probability-based standard, and cannot be built from “unreasonableness”, definitional disputes, or “recklessness” as a substitute for non-belief.
